Ductal carcinoma in situ (inside) is a Stage 0 non-invasive breast cancer that originates and is contained in the lining of the milk ducts. Ductal carcinoma in situ is the most common type of noninvasive breast cancer.
Invasive ductal carcinoma, the most common type of breast cancer, is characterized when the mutated cells spread from the ducts into the breast tissue.
If untreated, invasive ductal carcinoma can spread (metastasize) to other parts of the body.
Anybody can develop ductal carcinoma, but certain factors may increase your risk, such as:

If you're diagnosed with ductal carcinoma, treatment will depend on your general health and the results of your tests.
Your doctors and other specialists at the Magee-Womens Breast Cancer Program will work with you to consider your options and determine a course of action.
Surgery is often the primary treatment for breast cancer.
In many cases, we may also recommend additional therapies before (neo adjuvant) or after (adjuvant) surgery to control an aggressive cancer or to reduce the risk of recurrence.
Procedures and treatments for breast cancer may include:
Surgical Procedures | |
Mastectomy |
The surgical removal of part of the breast with a cancerous tumor (lumpectomy), breast tissue, or the entire breast. In some cases, lymph nodes are also removed. In rare cases, some of the chest muscles are removed as well. |
Sentinel lymph node biopsy |
A minimally invasive procedure to remove lymph node tissue in the armpit to check if existing breast cancer is spreading (metastasizing). Women diagnosed with an invasive breast cancer typically undergo a sentinel lymph node biopsy. |
Axillary lymph node dissection |
Surgery to remove all or a group of lymph nodes in the underarm (axilla), if your sentinel lymph node biopsy is positive for cancer. |
Additional Breast Cancer Therapies | |
Chemotherapy |
The administration of drugs to destroy the growth abilities of cancer cells. It is sometimes used with radiation therapy. |
Radiation therapy |
The use of beams of high-energy waves of ion particles to destroy the growth abilities of cancer cells. External radiation therapy directs rays at the tumor from outside a person's body. |
Hormone therapy |
The use of drugs that stop the production of certain hormones that the cancer needs to grow. |
